I re carpeted a class C including the engine cover and used contact cement. None of it ever came loose. You could try that combined with some carpet tacks or large staples. When using contact cement, keep the interior well ventilated. The other thing is to make sure the slide is not rubbing too hard on the flooring.
There is now some water-based latex contact cement available that doesn't produce anywhere near the fumes that traditional contact cement does. Unfortunately, while it's much nicer in that regard, in my experience it completely fails at actually holding things together. I suggest avoiding it. (Some claim it works better with very warm ambient temperatures.)
